The Research on the Dynamic Test of the Double Track Channel Beam

摘要：

　　In order to reduce the building height, the type of 31.2 meter double track channel beam is adopted on the railway bridge for the first time domestically.The channel beam is a kind of through bridge structure.Compared with box beam, T beam and slab beam, it has the advantages of lower building height, better soundproof and noise reduction, higher security protection perform ance and more economic cost.The compesitive utilization of its cross-section is good and it could prevent the derail vehicles from falling, which ensures necessary operation security.The dynamic test conducted in the thesis includes loading stress and dynamic factor, dynamic deflection and dy namic factor, the transverse vibration, vertical vibration and acceleration on the middle of the beam, and the transverse vibration of the bridge piers.The thesis analyses the test results and makes a conclusion.
